215,383, dated May 13, 1879 application nien January 2, 1879.`

To all whom it may concern Be it known that I, PAEDoN C. MCC/UNE, of Mount Etna, in the county of Adams and State of Iowa, have invented a new and useful Improvementin Horse-Powers, of which the following is a speciiication.

My invention relates to horizontal or sweep horse-powers; and the object is to apply a balance-wheel in connection with horse-powers used for thrashing grain in place of the tumbler-rods generally employed, so as to obtain a uniform and regular application of the power to the thrashing-machine, and prevent strain upon the machinery in stopping the power.

I make use of a balance-wheel placed upon a shaft from which the power is taken to drive the tlirashing-lnachine, which shaft is driven through the medium of pitman-rods and slides having spring-connections, connected with a counter-shaft that is geared to the masterwheel ot' the power, so that while the parts operate usually similarly to positive connections the spring-connections permit independent movement of the balance-wheel from the master-wheel in case of sudden jerks and in stopping the power.

In the accompanying drawings, Figure l is a general plan of the horse-power. Fig. 2 is a side elevation. Fig. 3 represents the slide.

Similar letters of reference indicate corresponding parts.

The power is set upon a bed, a, which may be on wheels for convenience of transportation.

The master-wheel b and its supporting-frame c are of usual character, and d is a pinion, operated by master-wheel 11, said pinion d being bea-rin gs c on frame c, and carries also a crankwheel, f.

The trame q represents the frame of a thrashing-machine. h is a'crauk-shatt, tted across frame g, and having keyed upon it the bala-ncewheel t' anda pulley, k, from which power is takento run the thrashing-machine or separator.

l is a pitman from the crank of shaft h, and m is a pitman from crank-Wheel f. These pitman-rods are connected respectively to crossheads n o, `thatare fitted to slide in the slideway p, and `the heads n o are connected to a central slide, q, which also moves in way 1J.

The connection between each head n o and slide q is made by a bolt, r, that passes loosely through the end of q into the head a or o, the nut of the bolt being in a mortise formed in the head. The bolts are loose, and carry spiral springs s t, which are rigid enough to make a firm, but elastic, connection of the parts, so that the revolution of pinion d shall be transmitted to shaft h and balance-wheel It is evident lthat by the above-described construction the `power is rendered more uniform and regular in its action, and the balance-wheel placed under perfect control. Any sudden lurches of the horse will not .aiect the thrashing-machine, as their force will be eX- pended in the spring-connections, and in case the power is stopped the momentum of the balance-wheel can carry shaft h around inde-` pendently of the power until it stops, the springconnections permitting such movement and restoring the parts to their normal position.

I do notlimit myself to the exact details of construction set forth, as they may be varied without departing from my invention. Belts may be used inplace of gearing, and the power used for other purposes than driving thrashing-machines. The pitman-rods may be attached to their cross-heads by a screw connected so that their length may be adjusted after the power and slides have been putin position at the place where they are to be used.

Having thus vdescribed my invention, I claim as new anddesire to secure by Letters Patent- In horse-powers, the balance-wheel crankshaft h, connected with the master-wheel b by the pitman l, the slides n, o, and q, held together by spring-bolts r, the pitman m, the crank-wheel j', and pinion d, as shown and described.
